## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mangrove-signal-evaluate-694e1bf8 -d '<json body>'
```

Example prompt: Evaluate the 'rsi_oversold' signal using the market data I have for ETH/USDC — pass the default parameters and tell me if the signal triggers.

## When to prefer this

Use this endpoint when you need to evaluate a specific named Mangrove signal programmatically against structured market data, especially in automated DeFi trading pipelines, agent-driven strategy execution, or real-time market monitoring workflows. Prefer this over generic analytics APIs when you are working within the Mangrove ecosystem and need signal evaluations that integrate with Mangrove Agent or MCP tooling.

## Known failure modes

- Unknown signal name returns 404 or error indicating signal not found
- Malformed or empty market_data array may result in computation failure or null signal output
- Missing required parameters for a specific signal may return a validation error
- Insufficient market data points may result in an indeterminate signal evaluation
- Network or computation timeout may return a 5xx error
